If there was a hypermassive singularity at the start of the universe then it would've just been a black hole and stayed stuck like that.

no because inflation of the universe wouldn't allow it

It's called the Great Vortex, and that's not a black hole. We're in the vortex now, the fact it spins is all the motion in the universe. The pressure is the external universe, and your trajectory through it is consc. Experience.

Oh ok I guess gravity just took a break during that time. I guess this is the arbitrary universe where laws of physics just change randomly.

space expanded from less than the size of an atom to 10 light years wide in less than a second. It was too fast and the matter was evenly distributed for gravity to do anything
>Modern theory asserts that the initial state of the universe, at the beginning of the Big Bang, was a singularity.[7] In this case, the universe did not collapse into a black hole, because currently-known calculations and density limits for gravitational collapse are usually based upon objects of relatively constant size, such as stars, and do not necessarily apply in the same way to rapidly expanding space such as the Big Bang

astrophysics don't work on intuition or fucking vibes

We don't know the initial rate of expansion, that is just pure conjecture.

Inflation had to happen within a certain time for one of the next phases to be able to start which was neutrino decoupling
https://en.wikipedia.org/wiki/Expansion_of_the_universe#Radiation_epoch
You can find the order that things occurred and their times in the table here
https://en.wikipedia.org/wiki/Chronology_of_the_universe
And the amount is mentioned here, with 10^26 being equivalent to a nanometer to 10 light years

That sounds right to me.

Black holes still produce radiation, so what do you mean by stuck?

Stuck for a long while

So by "stayed" stuck like that you meant that it wouldn't actually stay like that, it would eventually change?

It would've been a black hole and then scattered photons, not whatever we see today.

Yes. That's why we say we're fortunate that force of gravity is not stronger than it actually is.

However calling it a hypermassive singularity is not quite right given the state of space then

If the entire manifold was confined to the singularity, where would the radiation go, dumbass? Also, which experiment do you think demonstrated the veracity of the prediction that black holes emit radiation?
